WATER-*FILTER.

SPECIFICATION forming part of Letters Patent No. 723,639, dated Mlch 24, 1903- Application iiled June 9,1902. Serial No. 110,871. A (No model.)

To all whom. t may concern.-

Be it known that I, DWIGHT J. BLISS, a citizen of the United States, residing at Carthage,

in the county of Jasper and State of Missouri,

have invented certain .new and useful Im-V comparatively inexpensive of production, ef

cient in action, and also to provide means for thoroughly and effectively cleaning the surfaces of the filtering-cylinder.

With the above and other objects in view,V

which will readily appear as the nature of the invention is better understood, said invention consists in certain novel features of construction and combination and arrangement of parts, which will be hereinafter fully described, dened in the appended claims, and illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal vertical sectional View through my improved filter, illustrating the cleaner in operative position therewith. Fig. 2 is a horizontal sectional view on the line :vof Fig. 1, the cleaner being removed. Fig. 3 is a side elevation of the cleaner. Fig. 4 is a cross-section onthe line y y of Fig. 3. Fig. 5 is a cross-sectional view of a modified form of cleaner. Fig. 6 is a View of another form of cleaner. Fig. 7 is a view of still another form of cleaner.' y

In the drawings, 1 denotes the filter-casing, which may be of any suitable shape and capacity and which is shown in the present instance as consisting of a bucket provided with a -bail 2, by means of which it may be supported from above.

3 denotes the ltering-cylinder, which consists of a porous body having filtering-ducts 4, extending from its lower end upwardlyand ending short of the upper end'of the cylinder and arranged in annular order and provided with athrough-bore 5. This cylinder is seated upon a rubber gasket 6, located in lducts 4 and forming a chamber 7.

the bottom of. the filter-casing, said gasket surrounding .the lower ends of the filteringl This gasket forms a water-tight joint between the lower end of the cylinder and the casing and prevents water from entering the chamber 7 between the lower end of the cylinder and bottom of the casing. If desired, I may also place a cement packing '8 between the lower end of the cylinder and bottom of the casing and surrounding the rubber gasket 6.

9 denotes a tube or sleeve which extends through the central bore 5 with both ends and has its lower en'd projecting through the bottom of theeasing, and if t-he casing is designed to be supported upon a base 10 the lower end 'of said sleeve also projects through this base. Each end of the sleeve is screwthreaded, as shown in Fig. 1, and upon each .from said chamber into the sleeve, from which it discharges througha nipple 14, secured in the lower endo! said sleeve out through a pipe 15, connected to the lower end of said nipple.

The water to be filtered is placed in the casing and percolates through the porous cylinder into the ducts 4 and from these ducts discharges into the chamber 7 and is led off therefrom in the'inannerjust specified. The exterior surfaces of cylinders vof this character will in time become coated with foreign matter caught by the cylinder in the percolation of the water therethrough, and to remove this foreign matter or sediment I have provided a novel form of cleaner which may be readily attached to the cylinder and by means of which the exterior surfaces thereof may be thoroughly and expeditiously (cleaned.

The cleaner comprises an abrasivebody 16, preferably of a length corresponding to the length of the cylinder and secured in any suitable manner to a metal frame 17, preferably of channel-iron having a cross-sectional IOO . 2O in the sleeve 9.

18 is grasped and the abrasive body is caused grasped by the hand of the operator.

construction, as illustrated in Fig. 4.. An operating-bar 18 is pivoted by a bolt 19 to the frame 17 and has its upper end projecting upwardly within convenient lreach to be A pivotal post 20 is connected to the bar 18 by alink 21, and said post'is adapted to fit within the upper end of the sleeve 9. The link 21 has a horizontal row of apertures 2.2, through one of which extends a bolt 23, whereby as the filter-cylinder or abrasive body wears said body may be adjusted to the cylinder to corinpensate for said wear without changing ,the vertical position of the bar 18 with respect t0 the casing, and said bar will always be in a position to be freely revolved within the casing.

24 denotes a plug arranged within said sleeve near its lower end and is designed to prevent the escape of wafer from the pail through the sleeve when the pivotal post- 2O is removed, and iu Figs. 5, 6, and 7 I have shown modiiied forms of frames for securing the abrasive body, Figs. 5 and 6 showing an angle-iron frame and Fig. 7 showing a frame consisting ot' two bars between which the.

abrasive body and the bar 18 are clamped. Any other suitable form of frame may be provided without departing from the spirit of the invention.

The filtering-cylinder 3 may have on its lower end a series of radiating grooves or channels lh-affording communication between the central bore 5 and the filtering-ducts 4, so that should the lower ends of any of the ducts L be accidentally covered by the slipping ofthe rubber gasket or from other causes there still will be an outlet from such duct for the filtered water.

In operation when it is desired to clean the sides of the cylinder the frame is inserted in the casing between the walls of the lter and the interior wall of the casing, with the post The upper'end of the bar to rotate about the cylinder, and by applying outward pressure against the handle in the act of swinging it around the cylinder the pressure against the sides of the cylinder may be varied as the case may require, it being observed that the bar 18 has a pivotal connection with the link as well as With'the frame carrying the abrasive body, and this permits of a varying pressure being applied as the abrasive body is revolved around the cylinder.

From the foregoing description, taken in connection with the accompanyingdrawings, it is thought that the construction, mode of operation, and advantages of my improved water-lter will be readily apparent Without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle orsacrilicing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure'by Letters Patent, is-` l. The combination with a filter-casing and a filtering-cylinder arranged therein; of a bar of abrasive material extending substantially the full length ofthe filtering-cylinder, an operating-bar pivotally 'connected to the bar of abrasive4 material and pivotally and rotatably connected to the filtering-cylinder, substantially as described.

2. The combination with a filter-case and a iltering-cylinder arranged therein; of a bar of abrasivev material extending substantially the full length. ofthe filtering-cylinder, an operating-bar pivoted to the abrasive bar, a pivotal post connected to the cylinder, and a link connecting the pivotal post to the operatingbar, substantially as specified.

3. The combination with a iilter-case and a filtering-cylinder arranged therein; of a bar of abrasive material extending substantially the full length ofthe filtering-cylinder, an operating-bar pivoted to the abrasive bar, a pivotal post connected to the cylinder, and a link adjustably connecting the pivotal post to the operating-bar, substantially as set forth.

4. The combination with a filtering-case and a filtering-cylinder having a central bore, a post located within said bore, a bar of abrasive material extending substantially the full length oi" the filtering-cylinder, an operatingbar connected to the abrasive bar, a link one end of which is pivotally and adjustably connected to the operating-bar and the opposite end of which is fixed to said pivotal post, substantially as and forthe purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. Y

DWIGHT J. BLISS.
